Rapid earthquake magnitude classification via P-wave strains from borehole strainmeters and Distributed Acoustic Sensing [PDF]

Nature Communications
Distributed Acoustic Sensing (DAS) offers a promising approach for earthquake early warning (EEW) in settings where seismic networks are costly to maintain.

Previously hidden landslide processes revealed using distributed acoustic sensing with nanostrain-rate sensitivity [PDF]

Nature Communications
Landslides sometimes creep for decades before undergoing runaway acceleration and catastrophic failure. Observing and monitoring the evolution of strain in time and space is crucial to understand landslide processes, including the transition from slow to

Non-Invasive Methodological Approach to Detect and Characterize High-Risk Sinkholes in Urban Cover Evaporite Karst: Integrated Reflection Seismics, PS-InSAR, Leveling, 3D-GPR and Ancillary Data. A NE Italian Case Study

Remote Sensing, 2020
Sinkholes linked to cover evaporite karst in urban environments still represent a challenge in terms of their clear identification and mapping considering the rehash and man-made structures.

Gas and seismicity within the Istanbul seismic gap. [PDF]

Sci Rep, 2018
AbstractUnderstanding micro-seismicity is a critical question for earthquake hazard assessment. Since the devastating earthquakes of Izmit and Duzce in 1999, the seismicity along the submerged section of North Anatolian Fault within the Sea of Marmara (comprising the “Istanbul seismic gap”) has been extensively studied in order to infer its mechanical ...

Composite model of seismic monitoring data analysis during mining operations on the example of the Kukisvumchorrskoye deposit of AO Apatit

Записки Горного института, 2023
Geomechanical monitoring of the rock mass state is an actively developing branch of geomechanics, in which it is impossible to distinguish a single methodology and approaches for solving problems, collecting and analyzing data when developing seismic ...

Analysis of blasting impacts at the open pit Manastiriste near Topola on the monastery complex [PDF]

Mining and Metallurgy Engineering Bor, 2016
This paper discusses the problems associated with the negative effects that accompany blasting operations, and the certain conclusions were derived. One of the negative effects of blasting operations is the phenomenon of seismic action and its effects on

A synthetic study of acoustic full waveform inversion to improve seismic modelling of firn

Annals of Glaciology, 2022
The density structure of firn has implications for hydrological and climate modelling and for ice shelf stability. The firn structure can be evaluated from depth models of seismic velocity, widely obtained with Herglotz-Wiechert inversion (HWI), an ...

Application of first arrival seismic tomography in a glaciated basin: implications for paleo-ice stream development

Journal of Glaciology, 2023
Ice streams are sites of ice-sheet drainage and together with other processes, such as calving, have an impact on deglaciation rates and ice-sheet mass balance.
